Screenshot
I have a EntryCell and the color does not work properly in Desktop and Mobile. You can see in the screenshot that SwitchCell works properly so it may only EntryCell that has the issue.
XAML:
<ContentPage.Content>
<TableView Intent="Settings">
<TableRoot>
<TableSection Title="">
<EntryCell x:Name="labelUsername" Placeholder="" Label="User Name" Text="{Binding UserName}" Keyboard="Email" />
<local:PasswordEntry x:Name="labelPassword" Label="Password" Text="{Binding Password}"/>
<SwitchCell x:Name="labelOffline" Text="Offline/Non-Premium Account" On="{Binding IsOffline}" />
</TableSection>
</TableRoot>
</TableView>
</ContentPage.Content>
</ContentPage>
